A Japanese manufacturer is selling a kit from which you can make a gelatin/pudding dessert that looks like a shaking butt. For real.
The dessert is a tribute to the character of Shin Nohara on the Japanese manga series Crayon Shin-chan. The five-year-old Shin apparently shows his butt occasionally. I could not find any source to explain why a five-year-old would wear a red thong, so the tie-in with the character may be window dressing to make the product look respectable.
We can't say how it tastes, but you can watch a video of the process of making it at I New Idea. -via Everlasting Blort

It's likely not Shin-chan's butt though. His face is one of the other molds and even though he's 5 years old, he uses highly inappropriate language and often reacts to older/adult women in an inappropriate fashion. Shin-chan is one of those shows that seems like it could be a kid's show, but totally isn't. So, they wouldn't even attempt to hide the fact that this is a lady's backside that Shin-chan is reacting to.
